I'd be suprised if they could play 44.1Khz stereo audio directly from the
optical disk.  More than likely they just load up several megs of audio
directly into memory and play from there.  I don't have the specs on the
particular optical drive that comes with NeXT, but using the typical
specs given in the MIX Magazine article on optical drives, you can 
forget about recording or playing directly to optical disk,  at least
for the next year or two.
